Objective:

To know the prevalence of cognitive dysfunction (CD) and the pathology with which it is linked, in a sample of elderly people who live in residences, and to identify the relationship between the CD and the diagnosis associated with sociodemographic variables of sex, age and academic level.

Methodology:

Study quantitative, observational, descriptive, correlational and cross-sectional. Eight residential centers for socio-health care in the province of Pontevedra, Spain, participated. The study population was the newly elderly people registered (year 2017) who met the following requirements: being 60 years old or older, having a cognitive assessment performed on admission and a permanent CD diagnosis.

Results:

Out of 390 users, 312 presented CD (80%). The prevalence of CD in women was 86.2%, while in those with no or primary education it was 87%. It was estimated that CD derives from neurocognitive disorders (TNC) in 77.1% of cases. Depression was present in 27.5% of elderly people with CD.

Conclusions:

CD was present in 8 out of 10 elderly people, TNC is the most frequent illness associated CD, followed by depression. Being a woman and older as well as having a low level of education are related to a greater casuistry of CD.
